WRENCH- SPEGIFIQATION forming part of Letters Patent No. 753,862, datedMarch 8, 1904. Application filed March 19, 1903. Serial No. 148,522. (Nomodel.)

To all whom it may concern:

Be it known that we, ALBERT L. ELIEL, of Parlin, Middlesex county, New'Jersey, and JOHN LA BURT, of New York, Kings county,

5 New York, have invented certain new and useful Improvements inWrenches, of which the following is a full, clear, andexact'description.

This invention relates to a wrench that is of the class adjustable toembrace different-size I nuts or pipes, and the device is illustrated asapplied to a Stilson wrench; but of course it can be used on any kind ofadjustable wrench.

The object of the invention is to provide a means for releasing theadjustable jaw so that I it is free to slide at acertain point in thenuts rotation; and another object is to provide a means for returningthe adjustable jaw when it is in its free relation to the other jaw toits closed position when the wrench is not em- "2 bracing anything.

Reference is to be had to the accompanying drawings, forming part ofthis specification, in which similar numerals of reference refer tosimilar parts throughout the several views.

2 5 Figure 1 is a side view ofa wrench of our new style, and Fig. 2 is asection on the line 2 2 in Fig. 1. fied forms of a returning means.

In the drawings a'shanklO is provided, as

3 usual, with a jaw 11. A clip 12 is secured to the shank with a slightpivotal motion, with the pin 13 as a fulcrum. A shank 14 slides throughthe clip 12, and a jaw 15 is arranged to oppose the jaw 11. A thread 16is arranged on one edge of the shank l4, and in an opening 17 in theclip 12 is arranged a nut 18. This nut 18 is internally threaded, as at19,- and the thread is mutilated or cut away at the point 20 at adistance slightly in excess of 4 the width of the shank 14. When the nutis turned as. in Fig. 2, it provides a fine adjustment between the jaws11 and 15; but when it is turned so as to bring the mutilation 20opposite the thread 16 the shank 14 is free to be worked so as to adjustthe opposed jaws.

It will thus be seen that to get a quick and approximate adjustment thenut 18 is turned as last described and the shank 14 slid out to theFigs. 3 and 4 are views of modi required distance, and then a slightturn on the nut will provide an exact adjustment. 5 0

After the nut is used and it is desired to close it it is necessarysimply to turn the nut until the shank 14 is free, when a spring 21,secured to its bottom end and to the lower end of the shank lO, willoperate to pull it down, so as to close the wrench. When aworkmandesires to use the wrench with onehand if the other is engaged,he can turn the nut so as to free the shank 14, press the shank up fromthe bottom with his thumb, and catch the jaw 15 over the element to begrasped by the range, and the jaw 11 can be pulled to embrace theopposed side, and then the nut by a slight turn locks the wrench.Instead of the spring 21 we may employ the spring 22, (shown in dottedoutline in Fig. 1,) which can bear against a pin 23 on the shank 14 onthe outside, or the spring 22 can be arranged in a slot cut into eachshank.

Instead of a tension-spring, as shown in 21, we may encircle the shank14 by a spring 24, (shown in Fig. 3,) which can be arranged to exert apressure on a washer 25 on the end of the shank 14 and the bottom edgeof the clip 12. 7 5

Another way of drawing back the adjustable portion of the wrench isshown in Fig.

4, in which we attach a coil-spring 26 to the bottom edge of the shank14, the other end of the spring being coiled and fastened to a pin 27,supported on a plate or plates 28, attached to the bottom end of theshank 10. This spring is arranged to pull back the shank 14 by coilingup around the pin 27.

It will thus be evident that we have devised 5 an adjustable wrench thatis easily operated, quickly adjusted, simply arranged, and one that willbe normally closed and ready for instant manipulation.

Having thus described our invention, what 9 we claim as new, and desireto secure by Letters Patent, is

1. A wrench comprising a pair of shanks having opposed jaws, a thread onone of the said shanks, said shanks being adjustable to one another, anut for adjusting the jaws,

said nut having threads engaging with the thread on one of the shanks, amutilation in the thread of the nut to release the shank, when themutilation on the nut is in line with the thread of the shank, and aspring arranged on the outside and connecting the movable shank with theunthreaded shank to close the jaws when they are in sliding relation.

2. A wrench comprising a shank having a jaw on one end, a second shankadj ustabl arranged to the first shank and having a jaw 0pposed to thejaw on the first shank, a thread on one edge of the adjustable shank, anut on the unthreaded shank, said nut having a thread arranged to engagethe thread on the adjustable shank, a mutilation on the thread of thenut so that the adjustable jaw is released when the mutilation on thenut is in line with the thread on the shank, and a witnesses.
